TYPEWRITING MACHINE.

Application filed May 31,

My invention relates to typewriting and like machines and moreparticularly to paper controlling means.

This invention is in the nature of an improvement on the constructiondisclosed in each of the following applications:

Frederick A. Hart, Sr. No. 143,382 filed Oct. 22, 1926. \Valsoe & Hill,Sr. No. 121,13 1 filed July 8, 1926. Walsoe, Sr. No. 133,228filed-September 2, 1926. i

The present invention is intended primarily to improve the constructionsdisclosed in said previously filed applications and to provide anefficient, so-called three-sheet biller', and one which may be readilyconverted into either a so-called two-sheet or three-sheet biller, asdesired. 'A further object of the invention is to provide simple andefficient means whereby automatically controlled end stops for the papermay be adjusted to different set positions around the platen withoutafl'ecting the automatic control of saidstops.

To the above and other ends which will hereinafter appear, my inventionconsists in the features of construction, arrangements of parts andcombinations of devices set forth in the following description andparticularly pointed out in the appended claims.

The machine in which the features of the present invention are shownembodied is what is known on the market as a Remington front f'eedbookkeeping machine, which may or may not be equipped with automaticcarriage return mechanism such as disclosed in the patent to FrederickA. Hart No. 1,567,- 590, dated December 29, 1925. However, I have shownonly so much of said machine as is necessary to illustrate my inventionin its inclusion therein. It should be understood, however, that theinvention isnot restricted to embodiment in saidmachmebut is of generalapplication wherever found available.

As in the machines of the said previously filed applications the presentmachine is capable of a wide range of uses in connection with variousso-called billing operations and the like, where two or more work sheetsare to be correlated and printed at a single operation. However, I donot deem it necessary to describe specifically the many differentforms-of billing operations in which the machine may be used. It issufiicient for an understanding of the present invention to specificallydescribe one mode of billing that may be successfully carried out withthe aid of the present machine, and perhaps briefly refer to some of thevarious other methods in connection with which the machine may beemployed.

One method of using the machine, which will be specifically referred to,is its employment for simultaneously, or at one writing, making out abill or statement, making corresponding entries on the ledger sheetcarrylng the account, and on a record positioned to receive therequisite entries without disturbing the previously introduced re istersheet and companion carbon sheet. eans also are provided for thenquickly entering a statement sheet into the machine in front of theplaten and accuratelyl positioning it in proper correlation with t epreviously introduced ledger sheet and the-printing line. The entriesmay then be made on the statement sheet and these will be transferredthrough the interposed carbon sheets to the ledger and register sheets.If desired, additional entries may be made on the ledger sheet which arenotto appear on the statement or register sheet. The statement andledger sheets are then rapidly withdrawn from the machine withoutdisturbing theregister sheet and its companion carbon sheet and anotherledgersheet and statement sheet may then be quiclrly introduced, asbefore, and so on.

A line s acing operation effected by the return of t e carriage afterwriting a statement and making the corresponding entry on the ledger andregister sheets, advances the register sheet in position to receive amanifold copy of the next entry on the register sheet.

With the foregoing general explanation of the purpose and operation, Iwill proceed to describe the invention as it is embodied,

in the present instance, in said hereinbefore mentioned Remingtonmachine.

The frame of the machine includes the usual top plate 1 supporting hiredguide rails 2. The carriage or truck comprises front and rear guide orcross bars 3, united by end bars d and 5. The guide rails 2 and crossbars 3 are oppositely grooved to receive crossed anti-friction rollersby which the carriage is supported in the usual manner to travel fromside to side of the machineover the top plate 1.

A cylindrical platen '5' is mounted in the usual manner in a platenframe comprising the rigidly connected end plates 8 and 9; the platenframe being connected to the carriage by the usual shift links 10 and11. In the present instance, however, I contemplate writing only withupper case characters and the platen is, therefore, preferably held inthe upper case position. This may be readily done by screwing up thelowermost caseshift limiting screw-stops 12, thereby holding the platenshaft, or the buffer springs 13 which surround it, against the uppercaselimiting stops 12. This brings the printing line on the platen to aposition where the uppermost types on the usual type bars will registertherewith.

A. ribbon vibrator 17 is mounted to slide up and down in the usualmanner on a type bar center guide 18 secured to the type bar segment 19.The vibrator is actuated at each printing operation by the usualmechanism (see Fig. 5), whichincludes an arm 20, Said arm is pivoted at21 on a shift-able carrier or support 22 mounted on parallel links 23. Acontractile spring 24 tends to lift the shiftablesupport 22, and causesan anti-friction roller 25 carried thereby to bear upward against thelower edge of a bar 26. *This bar is secured to the carriage.

and. extends substantially throughout the length thereof. In the usualRemington machines the purpose of this construction is to cause theribbon vibrator to be shifted up and down with the platen in the caseshifting movements of the latter. In the present construction there isno such case shifting movements of the platen but the construction,nevertheless, lends itself to the accomlishment of another result whichwill heremafter appear.

As in the construction disclosed in my said previously filed applicationNo. 133,228, it is desirable when introducing a work sheet backwardlyinto the machine to lower the ribbon vibrator from its normal, Fig. 1,position. This is in order to enable the front paper deflector to. bemore conveniently moved to ehective position, as shown in Fig. 2. In thepresent construction I have employed the same means that are disclosed,in my said application for effecting this result. Thus, as in the priorconstruction, a bracket arm 27 extends forward from the shiftablesupport 22 and carries an'anti friction roller 28 at the upper endthereof. A. rock shaft 29 extends throughout the length of the carriageand is mounted at its ends in bearing openings in the end plates 8 and 9of the platen frame. This rock shaft 29 carries a plate 30 which ontendssubstantially throughout the length thereof and is bent down at itsforward edge to form a flange 31 which coacts with the anti-frictionroller 28. 'When the rock shaft 29, and the plate 30 carried thereby.are shifted by means to be hereinafter described, from the Fig. 1 to theFig. 2 position, the

\ shiftable support22 will be lowered against the power of its spring24, effecting a cor-- Coming now to the means for controlling and guidinthe work sheets, it will be observed in the first place that there areno paper feed rollers employed beneath the platen, such rollers as areemployed being located above the printin line, leaving the space beneaththe platen ree for the use of other devices. C

There are two curved paper deflectors 32 and 33 employed beneath theplaten, one arranged above the other and' maintalned spaced apart byintermediate spacing members or blocks 34 and 35 located near the endsthereof. Generally speaking, these deflectors conform to the curvatureof the platen or are substantially concentric therewith and extendsubstantially throughout the length of the platen. As thus constructedthere are two separate channels provided, one of which is the openchannel 36 between the two deflectors and which is bounded at its endsby separating merrbers 34 and 35, either or both of which may constituteside guides or gages for cooperation with a work sheet or sheetsintroduced into the channel 36. The other separated channel 37 isprovided between the under surface of the platen and the upper deflector32. The forward edge of the deflector 33 terminates in advance of theforward edge of the deflector 32, and has a slight downward curve incross section. The deflector 33 is continued up at the rear to providean upwardly and rearwardly extending paper table 38 which terminates ata considerable height above the platen. On the other hand, the deflector32 terminates in the rear of the platen at'a much lower point and belowthe top of the platen, where it is bent to form a loop 39 that looselysurrounds'a rod 40 fixedly connected at its ends to the end plates 8 and9 of the platen frame. In this manner the rigidly united deflectors 32and 33 are mounted on the rod 40 and have a slight pivotal movementthereon. A light wire spring 41 (Fig. 2) is connected by screws 42 and43 to a cross bar 44 of the platen frame, the spring being anchored atone end on the screw 42 and coiled around the stem of the screw 43. Theupper free end of the spring 41 is looped at 45, where it bears upwardagainst the bot-- tom of the deflector 33 and causes the forward edgeportion of the deflector 32 normally to be lightly pressed against theplaten, or against the interposed work sheet. In this manner the sheetsintroduced from the rear of the platen through the channel 37 will beheld snugly against the platen, and the sheets introduced into thechannel 36 will be prevented from entering the channel 37. By moving theupper end of the 'Of the lever 52 carries an paper table forward theforward end portions of the deflectors may be moved downward a limiteddistance, thus carrying the forward contact edge of the deflector 32away from the platen, and limited in its cast off movement by adjustablestops 46 as provided for in the construction disclosed in thehereinbefor'e mentioned Hart application.

In order to facilitate the backward introduction of the work sheets intothe mouth of the channel 36 from in front of the platen, there isprovided a guide, shield, or paper deflector 47 that is movable on thecarriage from a substantially horizontally disposed ineffectiveposition, shown in Fig. 1, to a downwardly and rearwardly inclined eifective position, shown in Fig. 2, and vice versa, as disclosed in saidpreviously filed applications. In order to receive these movements thedeflector is constructed and mounted, in the present instance, in thespeeifie manner disclosed in my said previously filed application.

Thus, the sheet metal deflector 47, Which extends substantiallythroughout thelength of the platen, is carried by parallel sheet metalsupporting arms 48 and 49. These supporting arms are pivotally mountedon forwardly projecting arms 50 secured to the end plates 8 and 9 of theplaten frame and which ma be re arded as arts of said end plates. he let-hand pivot pin'5l, on which the arm 48 turns, supports a bell cranklever 52 one arm of which carries a pin 53 by which a detachableconnection is made with the arm 48. The other arm 54 outwardly projected connecting pin 55 that is received and works in a slotted cam 56inan actuating arm 57. Said arm 57 is provided with a hub 58 (seeFig. 1) by'which it is secured to the hereinafter mentioned rock shaft29 by a set screw 58. The character of the slotted cam and theconstruction and the arrangement of the parts are such that a forwardpivotal movement of the arm 57 from the Fig. 1 to the Fig. 2 position,causes a pivotal movement of the deflector 47 in the opposite direction,or rearwardly from its normally ineffective position. This brings thedeflector 47 to the effective position, shown in Fig. 2, where itoverlaps and virtually forms a continuation of the deflector 33. In thismovement of the deflector 47 it passes from a position where it is outof the path of the type bars to a position where it is in the paththereof, and crosses the printing line where it is effective indirecting whereby said arm and the parts controlled thereby may beactuated at will. The arm 57 also stands in cooperative relationshipwith means for controlling the shifting movement of certain of the feedrollers, to be automatically controlled thereby, as will hereinafterclearly appear.

The actuating arm 57 constitutes one of two supporting arms for a wireline-indicator 60. Said indicator extends longitudinally throughout thelength of the platen and is adjustably connected to the arm 57 by meansof two clamping jaws 61 and 62, as disclosed in said Hart application.

The opposite end of the line indicating wire maybe adjustably secured toa second supporting arm 63 (see Fig. 1), as disclosed in said Hartapplication. The arm'63 is secured to the rock shaft 29 near therighthand end thereof. A coiled contractile spring 64: is connected atone end to the arm 57 and at its opposite end to a pin 65 extendinginward from, the end plate 8. This spring tends to return the arm 57 andthe parts connected therewith to the normal, Fig. 1, position.

The paper feeding mechanism embodied in the present constructionincludes a plurality of aligned paper feed rollers 66, arranged to coactwith the top of the platen and with work sheets introduced from the rearof the platen through the channel 37. Said feed rollers 66 coact withsaid sheets after the latter have passed above and beyond the printingline. The paper feed rollers 66, as shown in the present instance, areconstructed and mounted in the same general manner as in saidhereinbefore mentioned Hart application. Thus, the feed rollers aremounted for longitudinal adjustment along a supporting rod or spindle67, supported at its ends by forwardly extending arms 68 that arepivotally supported on the platen frame. Springs exert their forceagainst the arms 68 and thus cause the feed rollers 66 to bear againstthe platen, or certain only of the work sheets thereon. By swinging thesfpindle 67 upward and rear ward the said eed rollers are released.

ln the present machine it have included certain novel features of thepaper feed roller controllin means and also have ineluded certain of themeans disclosed in m said prior application by which the paper deflector47, line indicator 60 and ribbon vibrator 17 are automaticallycontrolled thereby. In some instances l have modified such mechanism,and in other instances I have combined therewith new features forconverting the machine into a so-called three-sheet biller andforautomatically controlling paper end stops as will now be de scribed.

In the present construction I have provided a pair of outside marginpaper feed rollers 69 and a pair of inside or intermediate margin paperfeed rollers 70 which coact with the platen above the printing line.Each of these feed rollers is constructed, mounted and controlled inpart in a like manner, and the description of one such feed roller andits mounting and control will apply to the others, except as hereinafterspecifically pointed out. Each of the feed rollers 69 and 70 is mountedto turn on a pivot 71 received between and riveted to two parallelroller carrying arms or slides 72. Each pair of slides 72 thus connectedare supported for rectilinear movement fore and aft of the machine byand between a pair of supporting arms 73 attached at their forward endsby screws 74 to a slotted sup porting block 75. In the slot in eachblock is received a supporting bar 76 that extends longitudinally of thecarriage, throughout,

or substantially throughout, the length thereof. This bar is secured tothe carriage by any suitable means, such as the screws 77 which connectthe bar to the front cross bar 3 of the carriage. Each block 7 5 is heldin place at any point to which it may be adjusted along the bar 76, bytwo set screws 78 received in tapped openings in the block and coactingat their inner ends with the supporting bar. The rear end portion ofeach supporting arm receive a headed guide pin 80 operatively connectedwith one of the arms 72 to support and guide it at its rear end. Theforward end portion of each arm 72 is also slotted at 81 to receive asupporting hub 82 therethrough, and thus support and guide each arm 72at its forward end. The shouldered stem of each of the guide pins 80passes loosely through a circular opening in the associated arm 72 andis rivetedat its inner end to one end of a toggle arm 83. The other endof each toggle arm or member 83 is pivoted at 84 to one end of acompanion toggle arm or member 85. The forward end of each toggle armintermediate spacing sleeve 86, 86, 86 or 86 as the case may be, saidsleeve being loosely supported on a rock shaft 87 and from both ends ofwhich spacing sleeve the hubs 82 extend. From what has been said it willbe understood that a turning movement of each sleeve 86, 86, 86 or 86will cause the toggle arms 85 attached thereto to be moved from anangular position, such as is indicated in Fig. 8, to a substantiallystraight line posi- 73 is slotted at 79 to 85 is riveted to one end ofan tion, such as is indicated in Figs. 1 and 6, v.

and vice'versa. In thus shifting each two pairs of companion togglemembers 83 and roller 69 or 7 0 will be moved in substantially straightline position the associated feed sure against the platen or the paperthereon,

86 and 86 and the rock shaft 87.

the slides 72 carrying the feed roller, moving longitudinally fore andaft of the machine. I prefer in practice to move the arms 83 and 85slightly over the straight line position in order to hold therollerspositively applied in their operativeposition. In' order to arrest eachcompanion air of toggle arms in proper position for th1s purpose Iprovide an inwardly extending lug 73 on each of the supporting arms 73,and with which either or both arms 83 and 85 of the associated togglemay coact to arrest the toggle in its straightened position.

It is desirable that the outer pair'of feed rollers 69 may be movedtogether to the platenythat the inner pair of feed rollers may be movedtogether to the platen, and that both the outside and inside pairs offeed rollers may be moved away from the platen together at a singleoperation. In order to attain these objects I provide the followingconstruction.

The rock shaft 87, hereinbefore referred to, extends throughout thelength of'the car riage and receives its support from the supportingarms 73. Preferably near each end of the shaft there is provided a hub88 secured to the shaft by a set screw 89. Connected to each hub 88 isan n standing finger piece 90 by which the shaft 8 ma be rocked eitherbackward to apply the eed rollers 69, or forward to release the feedrollers 69 and 70. A set screw 91 passes into a tapped opening in eachof the sleeves 86 and 86 for the outside pair of feed rollers 69,thereby at all times maintaining the toggles for these feed rollersconnected with the rock shaft 87 to be actuated thereby. That is to say,such toggles are always maintained connected to the shaft 87 except inthe event that either or both of the supporting blocks for these feedrollers are to be adjusted along the carriage longitudinally of theplaten. In such case it is merely necessary 7 to back up the screw 91for the sleeve of the feed roller to be thus adjusted. The screws 78 maythen be backed up and the block 75 with the parts carried thereby maythen be shifted along longitudinally of the shaft 87. When the properposition has been attained the screws 78 and 91 are again tightened tohold the parts in the new position to which they are adjusted along thecarriage and reestablish the connection between the sleeves In order tocontrol the to gles for the inner or intermediate pair. 0? feed rollers70,, I provide a collar 92 on the rock shaft 87 held to turn therewithby a set screw 93 received in a tapped opening in the collar and hearingat its inner end against the shaft. As best shown in Figs. 6 and 8, thiscollar is provided with a'projection 94, one side of which is adapted tocoact with a somewhat larger half circular projection 95 on the adjacenthub 82 of the sleeve 86. This provides a sort of a pin and slot, or lostmotion, connection between the shaft 87 and the sleeve 86, and betweenthe shaft 87 and toggles for the inner pair,of feed rollers 70 forpurposes which will hereinafter appear. Referring more particularly toFigs. 3 and 6 it will be seenthat the particular sleeve 86, which isconnected to the shaft 87 by the lost motion connection just described,has at its opposite end a half circu lar projection 96 that coact-s witha corresponding half-circular projection 97 on one end of a hollow shaft98. The hollow shaft 98 loosely surrounds and is supported by the shaft87 for independent turning movement thereon. An upstanding finger piece99 is secured to a hub 100, which in turn is secured to the hollow shaft98 by a set screw 101. The opposite end of this hollow shaft has a halfcircular projection 102 (Fig. 4) which engages a correspondingprojection 103 on the hub of the sleeve 86". It will be seen that inthis. manner the feed rollers 70, while individually mounted and capableofindividual adjustment longitudinally of the platen, are, nevertheless,connected to move together to andfifrom the platen, and that the same isalso true of the feed rollers 69. It should be understood that arelative adjustment between the feed rollers 70 would require the use ofhollow shafts 98 of different lengths but this is of little moment sincea machine, once set or arranged for a given establishment, ordinarilydoes not require any relative adjustment between the feed rollers 70.

It will be observed that I have provided 3 an interlockingprojection'103 on both ends of the sleeve 86 although only one is in useat any given time. This is in order that the sleeves 86 and '86 andtheparts controlled thereby may be interchangeably used one in the positionof the other.

The lost motion connection 94 and. 95

between the feed rollers 69iand 70 is such that the outside feed rollers69 may be first applied, as shown in Fig. 8, by moving either of thefinger. pieces 90 rearward. This results in turning the shaft 87 andcarrying the projection 94 to the position shownin Fig.8. At thistimethe project tion 94 is free from contact with either engaging edge ofthe projection 95. Consequently there is nothing to interfere with arearward movement of the finger piece 99 and a straightening of theassociated togq gles to. apply the feed rollers 70 with a positivepressure in thesame manner as the feed rollers 69, which 1s an importantfaetor. This movement results in bringing the lower front edge of theprojection. 95

against the rear contact edge of the projection 94. i It follows,therefore, that a forward movement of either finger piece 90 at thistime will turn the member 94 clockwise in Fig. 8, and carry with it themember 95- and the parts connected therewith. This results insimultaneously shifting all of the feed rollers 69 and 70 away from theplaten, as indicated in Fig. 2. From an inspection of this figure itwill be seen that the intermediate feed rollers 70 are shifted as farforward from the platen as the rollers 69, and that both pairs of feedrollers are shifted away from the platen a considerable distance, givingample room for the ready backward introduction of the work sheets intothe channel 36, which also is an important factor.

The means provided in the present instance for automatically controllingthe (leflector 47, the line indicator 60 and the ribbon vibrator 17 bythe shifting movements of the feed rollers into and out of eflectiveposition will now be described. I preferably employ for this purpose asingle auxiliary pair of toggle members of the same general character asthose hereinbefore described, and control such auxiliary toggle from therock shaft 87 and operatively connect it with the shifting arm 57. Thus,it will be seen upon reference to Figs. 1, 2 and 7 that a collar 104 isconnected by a set screw 105 to the left-hand end of the shaft 87. Thiscollar.is in the nature of a hub to which a toggle arm 106 is attached,and a reduced end of said collar receives a support in a circularbearing opening in a bracket or supporting arm 107. Said arm 107 issecured by screws 108 to a supporting block 109 adjustably held on thebar 76 by set screws 110. The rear end of the toggle arm or member 106is pivoted at 111 to the companion toggle member or arm 112 whichcarries at its rear end a headed pin 113. This pin is loosely receivedin a circular opening in a sliding, supporting or actuating arm or slide114, and also is seated in a slot 115 in the supporting arm 107 to slidefore and aft of the machine therein. The forward end portion of theslide 114 also is slotted at 116 to receive the reduced end of the hubor collar 104 and thus support and guide the slide at its forward end.The rear end of the slide carries a laterally projectin stud 117 whichis riveted thereto and in the forward-inove ment of the slide 114 coactswith the arm 57 and shifts it and the parts controlled thereby from theFig. 1 to the Fig. 2 position. The supporting arm 107 may also beprovided with a lug 118 to coact with and limit the straighteningmovement of the toggle arms 106 and 112.

It will be understood that the construction is such that when the feedrollers 69 are applied to hold, say, a ledger sheet L in its adjustedposition, the arm 57 is free to be actuated by its finger piece 59 with-B are introduced into the machine and into the channel 36 and correlatedwith reference to the previously introduced ledger sheet. As soon asthis is done the finger piece 59 may be released and the feed rollers 70are then applied to the bill sheet and hold the sheets in positionprepared to proceed with the writing. a

Any suitable paper end stops may be employed, if desired, to coact withthe ledger sheet in order to properly position it in the machine, suchmeans, for example, as are disclosed in the application of Frederick A.Hart, Sr. No. 172,685 filed March 4, 1927.

In the present instance I have provided automatically controlled paperend stops intended to coact with the bottom edges of rearwardlyintroduced bill sheets and the accompanying carbon sheets. Suchmechanism will now be described.

I prefer to employ two automatically controlled end stops, though anysuitable num ber may be employed. Inasmuch as each of these stops ismounted, adjusted and controlled in a like manner the description of onewill apply to both. A supporting strip 119 which is preferably made ofspring metal is slotted at the upper end portion thereof, as indicatedat 120 in Fig. 1, to receive the stems of headed binding screws 121. Thestems of these screws after passing through the slots 120 are threadedinto tapped openings in a spacing block 122, soldered or otherwisesecured to the back of the paper table near the upper end thereof. \Vhenthe screws 121 are tightened the heads thereof will bind against thesupporting strip and hold it in place. When said screws are loosened thesupporting strip and stop carried thereby may receive a slightadjustment fore and aft of the machine. The supporting strip 119 extendsdown in the rear of the paper tableand has its lower end portion curvedat 123 to conform generally to the curvature of the paper deflector 33.This curved portion of the supporting strip has a slot 124, as bestshown in Figs. 2 and 7, that extends lengthwise thereof and fore and aftof the machine. A paper end stop 125, in the nature of a pin, isprovided with a reduced threaded shank or stem that extends through theslot 124 in the supporting strip and receives thereon, back of thestrip, a Washer 126 and a binding nut 127. The stop pin when thussecured in place is adapted to pass through a slot 128 in the deflector33 and across the channel or passage 36 bein Fig. 1, this being thenormal position of said stop to which it is pressed by the force of thespring carrying strip. This conjusted on its carrier to the desiredposition, a

tightening of the nut 127 will-secure the stop in place thereon. Themeans just described affords a rather wide range or major-adjustment ofthe stop to accord with bill sheets, checks, etc. of differentdepths,'whereas the comparatively slight adjustment previously describedof the carrier, with theaid of clamping screws 121, may be, availed ofto. effect a'comparatively minute adjustment of the stop by reasonof themore ready access that may be had to this last mentioned adjustingmeans.

The supporting strip 119 has off-setfrom one side of the lower portionthereof a depending finger or arm 119*, as best shown in Figs. 1, 2 and7. This arm projects into the path ofafinger 129'secured to a crankarm130, the hub 131 of which is secured by a set screw 132 to a rock shaft133. This provides for effecting an adjustment of the finger 129 on therock shaft 133., This shaft extends throughout the length of thecarriage and has reduced ends received in bearing openings in the endplates 8 and 9. When the shaft 133 is turned clockwise in Fig. 1,thestop 125 is withdrawn to the ineffective, Fig.

2, position against the sprin force of the stopcarrying strip. When t eshaft 133 is released a light spring 134 tends toreturn said shaft tonormal position, thereby enabling the stop 125 to be projected by itsspringcarrier to the operative Fig. 1 positlon.

From an inspection of F ig. 4 it will be understood that in the presentinstance I have provided two end stops 125 and companion supports andreleasing devices therefor. These stops are aligned and located at adistance apart such as is required to coact with and arrest thecomparatively narrow bill and carbon sheets B and accurately gage them.1 v

A second contact edge or stop 140on the. member 135 coacts with the opposite side of the hub 139 to limitthe movement of the member in the opposite direction, as shown in Fig.2. The upper arm of the member 135 is slotted longitudinally at 141 toreceive a headed pin 142 on the rear end of a link 143. The forward endof this link is connected by a headed pivot screw 144 to the stud 117 onthe slide 114. It follows from this construction that an actuation ofthe shaft 87 to withdraw the feed rollers so that a ledger sheet may beintroduced, will automatically move the member 135 from the Fig. 1 tothe Fig. 2

position, thereby withdrawing thestops 125 arm 135,'such arm and thestops 125 con-.

trolled thereby, may be controlled independently of the automaticoperation thereof 1 with the feed rollers, a finger piece 145 beingprovidedon the arm 135 for this purpose; This independent shifting ofthe stops 125 toineffective position is occasionally required when, forexample, the stops 125 areadjusted for use in gagmg comparatively shortbill sheets and it may be neoessary now and then to introduce a longeror deeper bill By temporarily holding the end St0ps'125 in ineffectiveposition by the finger piece 145, the longer bill form may beintroduced, past the stops and gaged with reference to the printing lineand previously introduced ledger sheet with the aid of the lineindicator 60.

From an inspection of Fig. 4 it will be understood that the innersliding arm 72 of the left-hand feed roller, when the latter is ineffective position, constitutes a side edge gage for the sheets B' andB. It will be understood, moreover, that when such sheets .the feedrollers 69 have been applied to the ledger sheet, thereby conditioningthe parts so that the arm 72 in question may properlyfunction as a sideedge gage for the sheets (together with the parts carried by said gage,to be adjusted to proper position to coact'withthe sheets B. and B.

One manner of using the devices ofmy invention is as follows Y I Assumethat a register sheet B (Fig. 4) and its accompanying outside-carbonsheet B have been introduced through the chan- The fact that thesupporting block 75 for the left-hand feed roller 69 I are introduced,the feed rollers 70 have been nel 37 and properly positioned with theleading edges thereof beneath their feed rollers 66, and that theremainingparts are in' the Fig. '2 position. The operator thenintroduces a ledger sheet L from the front of the platen into thechannel 36 and accurate ly positions said sheet. An actuation of afinger piece 90 in a rearward direction results in straightening thetoggles to the Fig.

8 position and positively applying the feed rollers 69 against theplaten and against the margins of the previously introduced ledgersheet. At this time the finger piece 99 and the parts controlled therebyare in the Fig. 8 position, with the feed rollers 70 in the releasedposition. The bill or statement sheet B with an accompanying carbonsheet B may then be introduced from the front of the platen into thechannel 36, and bethe writing, and the matter written will be producedon the statement sheet and through the carbon sheets on the ledger andregister; sheets.

After the statement is written as described, the operator shifts thefinger piece 90 to the Fig. 2 position, therebyreleasingthe feed rollers69 and 70 and permitting ready withdrawal of the statement sheet, theaccompanying carbon sheet and the ledger sheet, and conditioningthe-machine for new sheets to replace these withdrawn. It will beunderstood that the hollow shaft 98, the feed rollers and theintermediate connections by which said feed rollers are actuated andmounted may be detached from the remaining parts. Therefore, such partsmay be applied or omitted, depending on the use to which the machine isto be put, as a two sheet or three-sheet biller. .v I have describedabove the means for moving-the feed rollers 69 into and out of contactwith the platen without reference to the automatic control by such meansof the line-indicator 60, the paper. deflector 47, and. the ribbonvibrator 17. The arrangement by which such automatic control is effectedis to extend the actuating arm 57 into the path of the bodily movablestud 117. As'the parts move from the Fig. 1 .to Fig. 2 position, thestud 117 .will coact (after a preliminary extent of lost motion) withthe actuating arm 57. This will result in automatically shifting theline indicator 60 to ineffem. tive position, in shifting the deflector47 to effective position and in lowering the ribbon vibrator 17 out ofthe path of the said deflector, all as represented in Fig. 2..

This same movement of the parts is effective to shift thelink 143 andthereby move the end stops 125 to ineffective position as shown in Fig.2, so that they Will not interfere with the-proper introduction of thenew ledger sheet in place, as hereinbefore. explained. It will be seenthat 'while the parts re ferred to above are automatically actuatedduring the withdrawal of the-feed rollers 69 from effective position,nevertheless, by an actuation of the finger piece 59, the line indicator60, deflector 47 and the ribbon vibrator 17 may be moved independentlyof the feed rollers 69 from the Fig. 1 to the Fig. 2 position, and whilesaid feed rollers remain applied to the platen.

At different times, depending on conditions of use of the machine, it isrequired that the deflector 47, line indicator 60, and ribbon vibrator17 be automatically moved to their respective positions when the feedrollers 69 and 70 are moved bodily back and forth between the Fig. 1 andthe F ig.'2 positions, and that said deflector, line indicator andribbon vibrator be independently controlled by the finger piece 59, asexplained above. But it is also essential at times that said feedrollers be released without moving the line indicator from its effectiveposition. This is necessary when, for example,

the line indicator is to be wholly relied upon to effect properadjustments in a line feed direction of the sheets (such as the ledgersheet 'L and bill or statement sheet B) introduced rearwardly in thechannel 36. To attain these ends the provision of lost motion betweenthe stud 117 and the arm 57 enables the rollers 69 and 70 to be moved ashort distance from the Fig. 1

position, without moving the line indicator 60 fromits indicatingposition, and without disturbing the deflector 47 and the ribbonvibrator 17.. Therefore, at this time the ledger sheet beneath therollers 69, and the subsequentlyintroduced statement sheet beneath thefeed rollers 70, may each be separately adjusted with reference to theline indicator 60.

In substantially inbefore indicated the machine may be employed as acheck-writing machine, at which time the sheet described above as aregister sheet would constitute a manifold record of the checks writtenand may constitute a pay roll sheet. In this event, however, no ledgersheet will be employed. The feed rollers 69 will be employed to coactwith the checks, and the finger piece 90 would not be manipulated,leaving the feed rollers 7 O ineffective.

Generally speaking, the sheet R described the same manner as hereaboveas. a register sheet, and which remains in the machine when the othersheets are removed and new ones inserted, may constitute a registersheet, a proof sheet, a sales sheet, a distributing sheet, or a pay rollsheet, depending on the use of the machine for different purposes.

In some instances the line indicator may be employed to position, in aline feed direction, each sheet introduced 'from in front of the plateninto the channel 36 when it is not feasible'or desirable, for one reasonor another, to employ end stops, or to employ end stops to coast with asheet corresponding to the ledger sheet.

By thepresent invention I have provided a construction which has provedrapid of operation, highly eflicient and reliable in use, which iscompact and comparatively simple in construction and can be manufacturedat comparatively small cost and be readily embodied in existingRemington machines without inodifying, or materially modifying, theexisting structural features of said machines.

.The claims in this case are specific to features not disclosed in anyof said hereinbefore mentioned applications. Various changes may be madein the construction and certain parts thereof may be employed withoutothers, without departmg from my invention as it is defined in theaccompanying claims.
